Shielding Factor of a Sphere with Finite Conductivity
Calculate the shielding factor of a hollow sphere with finite conductivity. The sphere is constructed from a lossy metal with a thickness of 2.5 nm.
An incident plane wave is defined from 1 MHz to 100 MHz. Use a single near field point located at the centre of the sphere to compute the shielding factor.

The shielding factor results are compared using the following solution methods:
- Method of moments (MoM)
- Finite element method (FEM)
Tip: It is recommended to create the models in the
order it is presented as each model uses its predecessor as a starting point. If
you would like to keep the different models, save each model to a new location
before starting a new sub example.
